Let me know if and when they spawn. Would like to get some from you. What size tank do you have them in and how big are they presently? Also how big were they when you acquired them and what size were they when they paired up and killed they others in the tank?
The guy I got them from had a wild pair that were fine for months in a 125 by themselves then one day the male just decided to kill the female, you just never know with these fish, true Dr. Jeykl and Mr. Hydes!
